2.2 Ecotec Swap (Page 1/2)
Trace26 JAN 08, 12:46 PM
Hello, I'm In the beginning of a 2.2 Ecotec swap into my 88 formula. Got the engine for free along with the rest of the car (08 HHR) and plan on using as much of the stock parts as possible so this swap can be done by others. I'll probably be going pretty slow but I'm going to make sure to keep this updated as I go.

I love this car I really just want something that's a good driver's car and I think this should accomplish that.

Here is a picture of the engine that I pulled yesterday!


Next will be to remove the cradle from the fiero and start comparing stuff.

Made any progress? I'm doing the same thing with a 2.2 from a 08 cobalt

Its funny, because my motor I pulled a couple days ago also has a roll of blue tape on it, and my driveway is in similar condition. lol

What are your plans for engine management?

I'm planning on retaining the stock ECU. I haven't decided yet if I'm going to keep the BCU. I think it's going to hinge around whether or not I decide to keep the cobalt gauges. I haven't finished my research yet, but I know they can be run standalone.

Stand alone Ecotec harnesses here.
Ecotec Wiring Harnesses

They have them for about 10 different Ecotec versions. If you need mounts Roger Thelin may be able to supply them.

in this link, there's a download for a DBW pedal adapter design, it allows the use of a ~06 Grand Prix accelerator pedal. you could send it to a laser cutter, or print the PDF version and trace it onto a piece of metal and drill/cut it yourself pretty easy. I can't confirm whether or not the grand prix pedal will work with the Ecotec pedal, but I suspect it would probably be fine.

I've seen all that. That's definitely the easy way to do it, but you're looking at $1800 in parts to get the engine mounted and running. I'm hoping to keep it below $300. My car isn't very nice and I got kinda screwed on it, looking to make it into a reliable daily beater. Hopefully someday a clean 88 formula will pop up in my area. I do have an 88 cradle in my garage, so that will probably go in the car. Not 100% sure on that yet though.

Done hijacking! I need my own thread...

Being blunt, trying to keep a swap like this under $300 is a pipe dream. Even just things like your costs in supplies for harness work on both the ecotec and fiero harness, fuel pump and lines good for 3bar, and even home made mounts and brackets can be inexpensive but will be around $100. Axles. Shift cables/bracket. Not to mention dealing with the stock ECU in most cases is not free. Most people go HPtuners, unless you know someone with a bulk licenses, its around $400 for the dongle and license to tune the ECU. Even if they do the work for free a box of donuts and a case of beer still add up. Intake run, tho that can be made easier with a V6 air filter box. Exhaust.

The most basic ECO swap will be ballpark about $1k.

With good planning it can and the time to do things your self you can do a very nice eco swap on a budget. But it is more involved than doing older engines and has lots of little things that need to change and if you don't expect or plan for them, its east to get caught off guard or all of a sudden be wayyy off budget.

In the case of the original poster, he got his ecotec 2.2 for free including the car it came in from an 08 HHR. So he has everything he needs except mounts for the cradle. If this is a manual transmission HHR then he can use axles from any manual trans Fiero. Pull the wiring harnesses out of the car, get the ignition switch out of the donor car steering column and you can make the car run without any tuning. If you are planning running NA then you do not need anything else, except a good welder. If the HHR is automatic, there are axles that fit, but I have no further info than that. The guy that found them went threw a pile of axles at a wreckers until he found a set that fit.

There is a place that will tune your ECM in to a stand alone unit for I think 400.00 and it is called Phil's Bug Shop in Grayson KY. As the name implies he specialises in VW but he does a lot of sand rail and dune buggy stuff, including swapping all kinds of engines in to buggys, including ecotecs and LS motors. He does not have a website, you have to phone for info. Do a youtube search for Ecotec swap dune buggy and most people mention Phil's.

If you can make your own cable mounts for the transmission, you can save some money there too but you might need custom cables, adding to the cost. I modified my shifter and made some rods that push and pull on the cables and then go under the engine and join up to the F23 to the stock cavalier mounts. But I cant use the stock Fiero console. It is all in the early part of my swap thread http://www.fiero.nl/forum/F.../HTML/000029-21.html
